You can participate in the hunt by using a free smartphone app that allows you to check in at the egg sculptures you find. Participants will have a chance to win jewel-encrusted Fabergé egg pendants valued at $30,000 and $48,000.

One man told WCBS 880’s Monica Miller that his virtual basket was almost full before noon.

“I have 22 so far,” the man said. “They had the Humpty Dumpty, they had something that looked like a space rock, but I prefer the real ones, like the coronation egg, the wedding egg.”

The egg hunt runs for three weeks.

All the eggs, which are more than 2 feet tall, will be displayed at Rockefeller Center from April 18 through April 25.
